Add tests for bug in mbedtls_x509_string_to_names()

Browse Source 
The commented out tests cause crashes (in different ways) until the bug
is fixed; the first two test are passing already and are here mostly to
provide a reference point.

The bug report was using programs/x509/cert_write, but string_to_names()
is what it was really targetting, which is better for automated tests.
The strings used are a minor adapation of those from the report.
